This ZRP 1994 cc Stroker Kit is designed for tuning and strengthening 06A-generation Audi / Volkswagen 1.8L Turbo 20V engines. The kit aims to increase cubic capacity by lengthening the stroke, while ensuring the mechanical integrity of the lower engine block in high-stress configurations (high torque, increased boost pressure, intensive use).
The ZRP forged stroker crankshaft is made of 4340 steel, a material known for its fatigue resistance and ability to withstand high cyclic loads. It is specified with a stroke of 92.80 mm, a journal diameter of 54.00 mm, and a crankpin diameter of 47.80 mm, for a weight of 13.80 kg. It is listed as compatible with Audi/Volkswagen 1.8T 20V 06A and 2.0 TFSI EA888 engines, with specific mention of engine codes 1.8T 20V and EA113.
The ZRP forged I-profile connecting rods are designed for Audi/Volkswagen 1.8 20V turbo and 2.0 TSI EA113 engines, with broad coverage of engine codes (AVC, ANB, AWU, AEB, APX, APY, BAM, AMK, AWM, AGU, AXX, BHZ, BGB, BWE, BUL, CDNB, BYK, BPJ, BWA, BWT). They feature a center-to-center length of 144.00 mm, a piston pin diameter of 20.00 mm, a conrod head diameter of 50.60 mm, and a head width of 24.89 mm. The included fasteners are made of ARP2000 with 3/8" threads, suitable for reinforced assemblies and high RPMs/loads. The listed weight is 0.52 kg. The package also includes a ZRP Supersport forged piston for Audi/Volkswagen 1.8L Turbo 20-valve engines, specified for the 06A engine.
This kit is intended for professionals seeking a cohesive lower-engine base for stroker mounting on a 1.8T 20V 06A engine, featuring forged components designed for reliability and mechanical endurance. The advertised cubic capacity of the kit is 1,994 cc. Machining, balancing, and checks for clearances and peripheral compatibility are not specified and must be verified based on the engine configuration and the intended modification.
